FFhUpj WATER-CLOSET VALVE.

Application filed July 15, 1913, Serial No. 779,211.

To all whom it may concern Be it known that I, GEORGE P. Bownnnn, a citizen of the United States, residing at Hempstead, in the county of Nassau, State of New York, have invented certain new and useful Improvements in -Water-Closet Valves; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled. in the art to which it appertains to make and use the same.

This invention relates to flushing valves for water closets and has for an object to provide a valve that will automatically flush the bowl upon the lid being closed and will automatically direct water from the street main into the closet tank when the lid is opened.

A further object is to provide an extremely simple double piston valve that will operate when raised to establish communication between the closet tank and the bowl and will operate when depressed to establish communication between the street main and the tank.

A still further object is to provide a valve of this character that will be extremely simple in construction, effective in operation, and will. not easily get out of order.

-With the above objects in view the invention consists of certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawings illustrating this invention: Figure l is a side elevation showing the application of my invention and showing the closet lid raised. Fig. 2 is a similar view showing the lid closed. Fig. 3 is a cross sectional view on the line 33 Fig. 1 through the ports in the upper piston of the valve. Fig. 4 is a vertical section through the device with the valve pistons in the position assumed when the lid is closed. Fig. 5 is a cross sectional view on the line 55 Fig. 2 showing the seat for the lower piston in bottom plan. Fig. 6 is a detail perspective view of the lower piston. Fig. 7 is a detail perspective View of the upper piston. Fig. 8 is a plan view of the device showing the parts illustrated in Fig. 1.

Referring now to the drawings in which Specification of Letters Patent.

Patented Dec. 22, 191st. Renewed November 19, 1914. Serial No. 872,947.

like characters of reference designate similar parts, 10 designates an ordinary water closet, 11 the hinged lid thereof, 12 the flush- 1ng tank, and 13 the flushing pipe, these parts being of ordinary character.

In carrying out my invention I provide a valt e casing lt including a body 15 having a lateral outlet 16 that is connected to the flushing pipe 13 and a second lateral outlet 17 that is connected to the bowl. A cap 18 is threaded on to the top of the body, and a second cap 19 is threaded on to the bottom of the body, the bottom cap having a lateral outlet 20 that is connected to the service pipe 21 from the street main.

A disk closure 22 is threaded into the body below the outlets thereof and is provided with orifices 23 therethrough, and is further provided on the bottom face with a ring 24: outside of the orifices, this ring a forming a valve seat.

A hollow piston 25 is mounted 011 a piston rod 26 and is provided in one side with an opening or port 27 that is adapted to register with the outlet 16 of the body that con nects with the flushing pipe 13, such registration taking place when the piston is at its lower limit of movement. The piston rod projects through the disk closure and is equipped below the latter with a disk valve 28 that engages with the bottom of the lower cap when the piston is at its lowest limit of movement and permits of water from the service pipe passing up through the orifices in the closure, through the port 27 of the upper piston and into the flushing pipe whereby to replenish the water supply in the .ushing tank 12.

When the pistonrod is raised the disk valve 28 seats on the ring 24 thereby closing the passages through the closure while at the same time the upper piston is moved up past both of the lateral outlets 16 and 17 of the body. In the latter position of the parts communication between the service pipe and flushing pipe is cut off by the lower piston and communication between the flushing pipe and the bowl is established through both of the lateral ports 16 and 17 of the body.

fulcrumed at one end on an angular bracket 30 that is fixed to the upper cap of the easing by means of a nut 31, the lever being pivoted intermediate the ends as shown at For actuating the piston rod, a lever 29 is I 32 upon the upper end of the piston rod and being equipped at the free end with a depending link 83 which is connected to a crank arm 34 that is in turn connected to the hinge of the lid as shown at 35. Upon the lid being raised the lever will depress the piston rod as shown in Fig. 1 whereby communication is established by the pistons between the service pipe and the flushing tank to fill the latter. Upon the lid being lowered the piston rod will be depressed by the lever whereby the pistons will cut off communication between the service pipe and flushing tank and establish communication between the flushing tank and bowl to flush the bowl.

From the above description it will be seen that I have provided an extremely simple and effective device of the character described which can be manufactured at minimum cost and will be formed of a few parts that will not easily get out of order.

hat is claimed, is

A combined supply and flush valve comprising a casing having lateral ports in the same horizontal plane for connection respectively to a flushing tank and a member to be flushed and having a port below said lateral ports for connection to a service pipe, a perforated diaphragm in said casing disposed GEORGE P.
